I pulled the heads and found they are numbered 462624 which makes them 76cc and as some people say the worst smog heads GM ever made. My intent was to disassemble and check them for cracks before reassembling with new valve seals. Or should I look for different heads?

With a cam upgrade can this engine make any power? It has a quadrajet and will get dual exhaust.

It will go in my 66 fleetside. All I am looking for is about 250 HP. I compare it to the the 65 Merc we had on the farm that had a 352 2 barrel with 208HP.

Thanks.
